Answer: 105.96
Explanation:
Sodium bicarbonate (Na2CO3)
Atomic mass of Sodium (Na) = 22.99
Atomic mass of Carbon (C) = 12.01
Atomic mass of oxygen = 15.99
Na2CO3 has a molar mass of (22.99x2) + 12.01 + (15.99x3) which is equal to
45.98 + 12.01 + 47.97 = 105.96
Thus, the molar mass of sodium bicarbonate is 105.96g/mol

Explanation:
If someone pours salt water on a plant that is supposed to receive fresh water, the effects on the plant are swift and severe, beginning with the draining of existing water out of the plant cell.<span> Then, the cell membrane separates from the cell wall in a process known as plasmolysis. Ultimately, the plant shrivels up and no longer thrives</span>
